CHARLES E. MARSTON, OF DOVER, NEW HAMPSHIRE.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 451,830, dated May 5, 1891.

Application filed November 15,1889. Serial No. 330,427. (No model.)

To all whom, it may concern:

Be it known that 1, CHARLES E. MARSTON, of Dover, in the county of Straitord and State of New Hampshire, have invented a new and Improved Radiator, of which the following is a full, clear, and exact description.

The invention is an improvement in that class of hot-water and steam radiators which are composed of a series of hollow superimposed sections.

I have aimed to provide a low-cost radiator whose separable sections have a maximum radiating-surface and a minimum weight of metal and whose interlocking flanges shall fit together in such a manner as to form joints adapted to conduct water of condensation downward without leak, as hereinafter more fully set forth.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view of a radiator embodying my invention. Fig. 2 is a central sectional elevation of the same, and Fig. 3 is a plan view of one of the radiator-sections.

In the drawings, 10 represents the base or standard which supports the several radiatorsections. Of these sections the lower one, which is shown at 11, is formed with a downwardly-extending flange 12,that is tapped to receive the combined induction and eduction pipe 13. At the lower edge of the flange 12 there is an inwardlyextending flange 14, forming a basin integral with the lower section, and from the flange let there extends downward a flange 15, the purpose of which will be hereinafter explained. The radiatorsection 11 is formed with an upwardly-extending flange 16 and with lower inclined.

walls 17 and upper inclined walls 18. The main radiator-sections, of which as many as necessary may be employed, are shown at 20, and these sections are formed with inclined walls 17 and 18 and with downwardly-extending flanges 21 and upwardly-extending flanges 16, the flanges 21 fitting within the flanges 16 or-16, as shown, so that the water of condensation will pass over the joint without entering it. All-of the radiator-sections the vertical flange 22 is attached at its transverse middle to the peripheral edge of a section, and that the flange 23 is radial with the edge. This symmetrical arrangement conduces to ornamental or attractive appearance of the radiator, and as the width of the vertical flange 22 does not exceed the thickness of the body of the section the latter occupies no more space vertically than it would if the said flange were absent. This is of considerable advantage in packing and shipping the radiator. The upper radiator-section 20 is formed with an inclined seat 2, upon which there is closely fitted a correspondingly-shaped flange 3, that is formed at the upper end of a pipe or tube 30, which said pipe extends downward through the radiator-sections, as clearly shown in Fig. 2. The lower end of the pipe or tube 30 is externally threaded to receive a clamping or binding nut 31, which bears against the flange 15, and,being turned home, serves to closely unite all of the radiator-sections.

In connection with the pipe or tube 30 I arrange a cold-air-delivery pipe 32. Above the upper section 2O I arrange an ornamental screen 34.

By constructing the radiator as above described I provide for a constant supply of freshly-heated air in the apartment in which the radiator is located, and at the same time I provide for an exceedingly satisfactory circulation of the heating medium, the gradual incline of the section-walls materially aiding in the matter of circulation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent The improved radiator consisting of the hollow superimposed sections formed with inclined walls and with upwardly and down wardly extending flanges 16 and 21 around the central openings, the lower flange of each section fitting within the upper one of the nected with said tube 30, all as shown and donext. section, the detachable open ended scribed. tube 30, having a head which is seated upon the upper section, a, nut 31, screwed on 5 the lower portion of said tube and bearing Witnesses:

against the lower radiator-section, and the ROBERT G. PIKE, cold-air-inlet pipe 32, which is suitably oon- SAMUEL S. PARKER.
